3 Claims.

This invention is an improved type of handle particularly adapted for use on oars for boats, as well as cranks for the usual conventional use of such items and, in fact, particularly adapted for use anywhere or on anyy device which is to be turned or rotated by hand.

The principal object of the invention is to provide a handle of the class described which will adequately and effectively prevent friction between the oar and the like and the hand with consequent abrasion or blistering. of the hand of the operator. y

Another and further object of the invention is to provide an article of the class described which will be simple in construction and which may be easily attached to conventional oars, cranks and the like.

A still further objectY of the invention is to pro- Vide a handle for oars, cranks and thel like which will not require frequent lubrication and which it is attached without much lubrication and without at any time binding or becoming fast to the principal object noise. f

A still further object of the invention is the provision of lan article of the described class which will permit the same to be attached or removed from an object with a minimum of effort.

Otherl and further objects of the invention will be apparent from the attached drawing and from the detailed specification which follows.

On the drawing:

Fig. l is a side elevational view of the complete,

f device attached to a conventional car or the like. Fig. 2 is a side elevational view of the internal sleeve which is indicated in Fig. 1V by dotted lines and forms a cylindrical base for the outer cylindrical sleeve portion.

Fig. 3 isa side elevational view of the outer cylindrical portion as it appears when removed from the inner cylindrical portion, a part of the same being broken away at the right of the drawing to show one of the retaining and lubricating rings shown in Fig. 6.

Fig. 4 is a side elevational view of the retaining ring which holds the portion shown in Fig. 3 securely mounted on that portion shown in Fig. 2.

Fig. 5 is a view of the threaded bolt or rivet which serves to hold the ring shown in Fig. 4 securely mounted to the oar, crank or the like.

Fig. 6 is` a view of a retaining ring, two of which, as hereinafter indicated, are used in my invention for the purposes hereinafter set forth.

to which it is attached, or causingr 'I'he letter A is used to indicate a conventional oar, crank or the like. When my device is used on an oar a conventional oar lock must be used with a pin extending through the oar to act as a fulcrum for the oar. Mounted thereon and retained thereon substantially as shown in Fig. l, is the inner cylindrical member indicated by the numeral I, more particularly shown in Fig. 2.

'Ihe inner cylindrical portion I is a substantially elongated tube, circular in cross section, adapted to be forced on to that portion of the oar or the like indicated by the letter A. Permanently mounted thereon or formed integral therewith at its outer end is an annular ring of metal forming an end shoulder indicated by the numeral Ia.. Portion la` is substantially larger in cross section than is the remaining part of member I and is adapted to form a retaining end to securely mount thereon the out cylindrical member shown in Fig. 3.

Portion I has a pair of apertures therein in cross registry with one another, indicated by the numeral Ib, through which the pin or rivet shown in Fig. 5 may be inserted.

Shown in Fig. 3 is the outer cylindrical member indicated by the numeral 2 which is adapted, as shown in Fig. 1, to slidably t over member I and is adapted to form the portion which is gripped by the hand and which will rotate with the hand of the operator. Cylindrical portion 2 is slightly shorter in its longitudinal dimension than cylindrical portion I, portion. I being longer than portion 2 to permit the pin, rivet or bolt shown in Fig. 5 and indicated by numeral 6, to be placed through it and that ring member or portion shown in Fig. 4.

As shown in Fig. 3, cylindrical member 2 has a smaller inner diameter at its intermediate part and beginning a short distance from each end thereof than the inner diameter at the ends thereof and this central portion is thus widened at each end to form an offset annular shoulder indicated by the numeral 2a forming a base for the ring 1 shown on the drawing. The larger end openings forming the shoulder 2a against which ring 1 rests are shown formed to permit that portion indicated by the numeral Ia in Fig. 2 to pass thereinto at one end substantially as shown in Fig. 1, and at the opposite end to permit the annular ring 5 to be placed partially therein as shown in Fig. 1, a part of ring 5 extending outside of casing 2 to permit the rivet or bolt 6 to be inserted through apertures 5a in said ring and apertures Ib in the inner cylindrical portion and through the oar or the like securely mounting the entire construction in the portion A.

As shown on the drawing, a pair of metal rings 1 are placed in cylindrical portion 2 against the annular shoulder portion 2a, these serving to provide a self-lubricating bearing which will permit portion 2 to rotate easily upon portion I Without the necessity of lubricating the parts and without causing appreciable noise, the ring 'I being formed of brass, bronze or other soft or selflubricating material or metal.

'Ihe cylindrical or annular ring 5 shown in Fig. 4, as shown on the drawing, slightly longer than the part Ia of cylindrical member I, the same being adapted to fit into portion 2 and rest against ring 'I and also, as shown in Fig. 1, to extend out beyond the innermost extending end of casing 2, exposing the pair of apertures 5a in cross registry with one another and adapted, as shown, to fall into registry with the similar apertures Ib in portion I permitting bolt or rivet 6 to be inserted therethrough and through the oar or the like and adapting the entire construction to be easily yet solidly mounted on to that portion of the oar or the like indicated by the letter-A.

To mount my invention on an oar or similar article it is necessary to place the ring 5 on the article. Cylindrical portion 2 with the rings 1, placed in manner shown on the drawing, may then be passed over the portion of the oar or the like, extending out rearwardly of the ring 5. Portion I may then be placed or forced upon the oar, care being taken that apertures I b` of portion or member I and apertures 5a of portion or member 5 fall into registry one with the other.

The entire construction is then adjusted in its relative position on the oar handle and the relative position of the said parts to one another adjusted so that portion Ia of cylindrical member i Will loosely and rotatably contact ring 1 on shoulder 2a at the outmost extending portion of the handle, and further adjusted so that portion 5 will loosely contact ring I on the shoulder portion 2a. of the innermost end of the entire construction. In such position cylindrical portion 2 will rotate easily upon portions I, Ia. and 5l substantially retained thereon.

Apertures 5a. will then be exposed and if properly adjusted will be in registry with apertures I bl of portion I which over-extends portion 2 and the bolt 6 may, by drilling an appropriate hole through the oar or other base A, be placed through such hole, the nut screwed to position thus securely and rigidly retaining the entire construction on the oar or the like.

Various changes may be made in the embodiment of the invention herein specifically described without departing from or sacrificing any of the advantages of the invention or any features thereof, and nothing herein shall be construed as limitations upon the invention, its concept or structural embodiment as to the whole or any part thereof except as defined in the appended claims.

I claim:

1. In a device of the described class, the combination of a relatively long inner cylindrical tube having an annular end enlargement forming an annular Shoulder, a ring in juxtaposition to said annular shoulder, an outer cylindrical tube enclosing said inner cylindrical tube, offset annular shoulders at each end of said outer cylindrical tube, a ring in juxtaposition to said innermost annular shoulder, a retaining ring insertable into said outer cylindrical tube, said retaining ring and said inner cylindrical tube being provided with apertures in cross registry with one another, and a bolt insertable therethrough and through the article on which said device is to be mounted adapted to fasten said device in operable position.

2. In a device of the described class, the combination of an outer hollow cylindrical portion having a pair of end apertures of greater diameter thanvthe diameter of the central portion thereof forming a pair of internal annular shoulders, a pair of friction reducing members mounted on said shoulders, an inner cylindrical portion having a relatively enlarged end portion insertable into said outer cylindrical portion and retained at one end by one of the internal annular shoulders in said outer cylindrical portion, said inner cylindrical portion being relatively longer than said outer cylindrical portion, an annular ring larger than said inner cylindrical portion and slidably insertable on that part of the inner cylindrical portion over-extending the outer cylindrical portion and contacting one of said friction reducing members, said inner cylindrical member and said annular ring havingY apertures in cross registry with one another and means to retain the construction aforementioned on an oar or the like.

3. In a device of the described class, the combination of an inner tube member, an annular end enlargement on said inner tube member, an outer tube member for enclosing said inner tube member substantially throughout its length and being provided with a pair of annular recesses at each end thereof forming internal annular shoulders, an annular retaining piece for placement on said inner tube member and for insertion into one annular end recess in said outer tube member for retaining both said tubes in xed but rotatable relation to one another, and means for mounting the entire construction aforesaid on an oar or the like.
